"Application filed August 10,1917. "Serial 1101185, 198.

"Be it known that I, ERNEST- FUCHS, of 15 Rue Gustave Sandoz, atBillanc-ourt, De-

partment of the Seine, France, citizen of the French Republic, haveinvented certain new and useful Improvements in Apparatus for ChargingIngots i'nOvens; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in'the art to which it appertains to 'makeand use thesame.

"The present invention has for. its object to provide an arrangement forautomatically charging into an oven cylindrical objects or ingots ofuniform size which enables the same pieces heated to be dischargedautomatically at the other end of the oven.

The principal part of the apparatus con sists of a pivoted block adaptedto strike a row of articles placed side by side horizontally in the ovenalong the whole length of the bottom thereof, the blow given by saidblock advancing the whole row of objects and bringing about at thewithdrawing end of the oven and at each stroke the exit and withdrawalof the last ingot of the row.

The said block is of suitable form so as to be capable at the same timeof regulating the supply of ingots placed in a charging cone in the formof a funnel.

The apparatus may be operated from a distance manually by the workmanhandling the discharge and the disposal of the heated objects.

The accompanying drawings show by wav of example an installationcomprising the above apparatus especially adapted for the re-heating ofshells which it is desired to temper.

Figure 1 is a view in vertical section illustrating the oven, the ingotsand the apparatus in question.

Fig. 2 is a detail view showing the block in contact with the firstingot of the horizontal row.

Fig. 3 is a similar view in which the block is at the extreme point ofits stroke.

In Fig. 1 A. indicates the bottom of the oven on which the ingots rest.The bottom A is slightly inclined toward the exit so as to facilitatethe movement of the ingots. At its lower extremity a sill B maintainsthe row of ingots which are placed side by side as far as the upperextremity or charging oiifice'of the oven floor. The chargingapfparatus'comprises a vertlcal passage or charging cone C combined witha horizontal guide D, and includes a part E forming a restw'hichsupports the pile of ingots placed in the vertical passage.

A block F of suitable weight, mounted on alever G pivoted at I to theupper portion of the oven, carries two projecting parts H and (see Fig.2) of such a length that the partI-I will strike the first ingot Q ofthe row to beheatedbefore the part H comes in contact with the ingot Pplaced on the re The lever G, pivoted at I, is prolonged by a lever J,pivoted to a rod K, connected at its other end to a bell-crank lever L,capable of rotating about a pivotal point M.

A rod with a handle N, within reach of the workman supervising thetempering operation, enables, by the aid of the pivoted system describedabove, a pendulum movement away from the discharging apparatus to beimparted to the block F of such extent that on being released by lettinggo the handle N the block strikes the first ingot of the rowsufliciently hard to displace all the in gots on the floor of the oven.

A stop 0 limits the amplitude of the movement in order that thedisplacement of the horizontal row may be exactly equal to the diameterof the ingots.

Owing to the projecting part H the block, toward the end of its stroke,knocks the ingot P oil the rest E on which it is placed. At this timethe vertical pile which is in the passage C is kept up by the projectionH (see Fig. 3) and the ingot P, which tends to go to the back of therow, is stopped by the extremity of the projection H of the hammer.

By again actuating the handle N the hammer is withdrawn, which enablesthe ingot P to go into position at the back of the row and the ingotswhich are in the vertical passage to again rest on the piece E. Therelative position of the ingots to be charged and the ingots already inthe oven is the same as at the commencement of the operation, andanother pull on the handle N sufiices to cause another ingot to enterthe oven.

It must be noted that at each entry of a new ingot into the oven acorresponding automatic exit of a heated piece takes place at the otherextremity.

The invention is not, of course, limited to the apparatus describedabove, and it must be understood that the right is reserved to applymodifications, principally in the control mechanism of the block F.

I claim: I

1. The combination with an oven having an ingot supporting surface, ofan abutment at one end thereof, a feed hopper at the opposite endthereof arranged to feed a row of ingots to the supporting surface,means to impart a blow to the last ingot of said row, said means beingarranged to permit an additional ingot to pass to said row, and meansfor causing said ingot to pass to said last mentioned means.

2. The combination with an oven having an ingot supporting surface, ofan abutment at the exit end thereof arranged to engage the last of a rowof ingots, a hopper for feeding the ingots to said surface, means forsupporting a supply of ingots above said ment at one end thereof, ahopper at the oppositeend thereof having 'apassageway communicat ng withsaid supporting surface, a 11p in said hopperfor supporting a supply ofingots and a block having means adapted to engage the endmost ingot insaid passageway to impart a blow thereto and having means to engage thelowermost ingot on said lip to cause the same to drop tosaid passageway.V

In testimony whereof I affix my, signature, in presence of twowitnesses. V
